I think It is.
In all seriousness, someone has been checking game files and they stumbled across this. Could this be confirming what they said in the last announcement about other releases? PS5 leaks.
Do you think that it would be released on Sony? Would you want them to? (I know they released the Vita version, and Sony and PSO have always had a decent relationship.) Do you think they would do cross-play considering how things have been going with them? I am curious as to how many people would like it or think Sony would have handled the release better. I would welcome cross play if it ever got released. Steam/International 1st priority however.)
